-With ythese and other objects in vie\v, the invention consists of the lnoyel features of construction and the combination and arrangement of parts "liereinafter' fully described and claimed, and illustrated in the accompanying drawing, in Which-- Figure 1 is a side elevation illust-rating the application of the device; Fig.l 2 is an enlarved vertical section through the helmet and" the air tank; and Fig. 3 is asection taken on vthe line 3-3 'of Fig. 2.-

Referring more particularly to the drawings 5V indicates my improved helmet which comprises the regular metallic head casing 6 andthe neck piece 7 which is ada ted to be suitably fastened to the divers suit. The casing 6 is provided in its front and sides with the heavy glass lenses 8 through which the diver-,may obtain a clear and distinct view of his surroundings.` I preferably form the helmet casing at its top with Va knife blade 9,-the body oi which is tubular and is provided in its front with a lens 10 through which thelight is emitted from an'electric bulbI 11 arranged therein.

The supply wire 15 extends above the surface of the Water and is suitably connected with the source of current. The other of the fans 17 is electrically connected to the batteries 1S carried in the bottom ofthe, supply tank. This fan undernormal conditions "is not-'in operation and -is controlled by means of a switch 19 arranged in the 'interior ofthe front of the helmet.. The battery of the 'fan 14=is also connected to the switch 20 adjacent to the switch 19. Another switch 21`is also -arrangedin the helmet and controls the-supply of current to the electric i light bulb 11 arranged in the top of the helmet casing.' These switches 19, 20, and21 are arranged adjacent to each other and are `adapted to be operated by the diver by using his teeth to turn' the same. In this manner he may always obtain an ample supply of fresh air, the air being driven by the fans through the tube 13 into the helmet and returned back to the su Jply tank through the branch tube 13. In tie event that the Wire 15 should become entangled in the debris of a wrecked vessel around which the diver is Working, he may readily put the other of the fans v17 in operation by simply turning the switch 19.

From-the foregoing it is believed that the construction, operation and many advantages of my improved diver-s helmet will be apparent Without. necessitating a more extended description. The device is simple, light and of great convenience and efficiency in use. The necessity of pumping air through tubes connected to the divers helmet iseliminated and he is enabled to remain under the surface of the Water fora great length of time Without requiring an additional air supply.

While I have shown and described the preferable en'ibodiment of my invention, it will be understood that the same is susceptible of many minor modifications without de art-ing from the essential features or saeri icing any of the advantages thereof.

2. A divers helmet comprising a casing I having lenses in the sidesand front thereof,

' in combination with un air supply'tank earried by the diver, tubes connecting said tank with the helmet, and electrically actuated 'fans in said tank and under the cont-rol of the diver adapted to supply a constantly circulating current of air to the helmet.

3. A divers helmet comprising-a helmet easing having vision lenses therein, an electric bulb in the top'of said casing, in coniA bination with an air supply tank carried by the diver, tubes connecting said tank and helmet, electrically operated fans in said tank, adapted to supply a constantly circulatin current of air to the helmet and switc ies in said helmet adapted to be actuated by the diver to control sa'd fans and the lightin said helmet.

4. A' divers helmet compris ng a casing having vision lenses in its sides 'ind front, a tubular light casing formed upo thetnp of the first named casing having a lens in one end, an electric light bulb in said last named casing, said latter casing being' formed upon its top with a knife edge, in combiiuxtion with an air supply tank arranged upon the back of the diver, tubes connecting said tank to the back of the helmet, a plurality of electric batteries in said tank,` av fan supported upon opposite sidesof the tank, a wire connecting one of said fans with the source 0f electric sup-ply exteriorly of ,the t'.1nk,eon neetio'ns between the batteries and the other of said fans, connections between said batteries and the electric light bulb in the' helmet, and electric switches arranged in the interior of4 the front of the helmet easing a-nd adapted tov be actuated by the divers teeth to control said light and the fans in said tank whereby Ial constantly circulating current of air is supplied to- Said helmet.
